I'd ask my dear little Koko why she prefers almost any place other than the litter box. And I'd ask her if she's in any pain at all, or if there was anything more I could do for her to make her more comfortable. And I'd tell her that even if she doesn't like the litter pan, I still love her.
And I'd tell Kohl that he has to stop bullying the other cats. And maybe I could get him understand that I don't care if he is the only male cat, he's not the dominant cat in the house - that would be ME and he has to follow my rules. And I'd tell him that even though he is a bully, I'm still glad he found us and came to live with us.
And I'd tell my Sam and Amber cats that I'm really sorry they feel pushed around by Kohl, and they don't spend time in the places that they used to any more. And that just because he's here and a bully doesn't mean I don't love them, or that they're any less a part of this family.
Actually Koko does talk to me. She lets me know when she's not feeling well, or when she's lonely. She has a specific meow that's just for me - it sounds like ma-ma - and when she doesn't know where I am she wanders around the house calling me. When I remind her where I am she comes running, and will climb on my lap, put her nose to mine and say "ma". She's very sweet.
